UNITED STATES f PATENT UFFICE smumnumss SPECTACLE Louis John Page, Hollis. N. Y., assignor to Olive Page, Hollis, N. 'Y. Application August so, mo. semi rio. ssssoo l s claims. (ci. ss-m This invention relates to animprovement in securing ophthalmicv lenses to a spectacle mounting. The improvement resides in thenovel means of securing the lenses to the mounting.

One of the objects of my invention is to facilitate the mounting of lenses.

Another object is to provide a strap shoulder which creates pressure along the whole length of contact with the lens.

Another object of my invention is to use the temple support arm as a check to lens wobble.

Another object of my invention is `to create a better looking, stronger, and cheaper to manufacture spectacle mounting.

These and other objects and advantages reside in the combination of such novel 'features of construction which will be more iully de'- scribed and explained in the appended claims.

Referring to the drawing:

Figure l is a perspective view of a pair of spectacles embodying my invention.

Figure 2 is a top fragmentary view ofthe mounting shown in Figure l. e

Figure 3 is a cross sectional view on the line 3-3 in Figure l.

Referring to Figure 1 the bridge 8 supports two members 9 and 9' which are parts of the arms 3 and 3. The arms 3 and 3'terminate in loops 2 and 2' forming clamps. To the members 9 and 9 are attached strap ears 4 and I'. A pair of lenses l and I' are secured in position by the screws I and lll' which pass through washers and 8' positioned on the front surface over holes in the lenses I and l'. The screws l0 and Il'. after passing through the washers and the holes in the lenses, are threaded into the strap ears I and l'. The loops 2 and 2' iit into notches formed in the temporal edges of lenses I and l. To the rear side near the temporal end of the arms 3 and 3 are attached endpieces 6 and 6' which in turn support the temples 1 and 'l' Referring to Figure 2 the arm 3' .is shown in the edge of in the temporal edge of the lens i'. 'Ihe lens I' is attached to the arm 3 by means o f the strap ear I. The lens ll is secured to the strap ear 4 by means of the screw I0' and the washer i'. An endpiece 8' is attached tn the temporal side of `the arm 3'. A temple 1' is pivotally attached to the endpiece 8'.

'Referring to Figure 3 the lens l is shown in position in relation to the member 9' and strap ear I'. The inner angle of member 9' and strap ear l is smaller when the mounting is not attached to the lens. When the screw Il' is threaded into the strap ear 4' it pulls the strap ear l'against the rear surface of the lens i' so that the member '9' exerts pressure along the bevel of the lens I?. The upright part or the bridge is shown as l..

In mounting lenses, the in a notch formed in the temporal edge of the lens. The strap ear is then positioned over a hole drilled near the nasal edge of the lens. In positioning the strap ear it is necessary to put some tension on the arm 3 since the distance I between the loop 2 and the strap ear l is shorter -said screws inserted .lens holes edge oi said before mounting than after mounting. A screw is inserted through a washer, through the hole in the lens and threaded into the strap ear. Upon screwing the strap ear against the rear 'surface of the lens, the arm 3 engages abevel formed along that part of the lens.

It is apparent that manychanges could be made, such as, the bridge may have ,various designs and may be attached to the lens in the most suitable manner; dierent types oi straps may be combined with the arms; the straps may be attached lat several positions; the arms may have various shapes and bends; the endpieces may be attached at diirerent points. Therefore it is intended that the matter contained in the above specification is not limiting.

I claim:

1. An ophthalmic mounting comprising a bridge, arms, said arms'being attached to said bridge, said arms being' rections and terminating in a forward projecting part forming a clamp, endpieces, said endpieces being attached near the outer end on the rear side of said arms, temples, said temples pivotally mounted to said endpieces. strap ears, said strap ears being attached to the inner side of said arms opposite to said bridge, the plane of said strap ear forming an obtuse angle with the plane of the surface of the adjacent arm'part, said strap ear having a threaded hole, lenses, said lenses being prepared with along inner bevel, a hole and a notch, said clamp positioned in said notch, said strap ear positioned over said hole, washers, each of said `washers positioned over said hole on the opposite surface of said lens. screws', through said washers and and screwed into said strap ears. the arm partv adjacent said strap ear pressing against the lens bevel, securing said lenses in position in said mounting.

2. An ophthalmic mounting, comprising. in combination with a pair of prepared lenses, said loop 2 is positioned 'directed in opposite di- .wm www. .am md .YP m..d dde.. .l .www .mmm wmmmmmmmmmmm m E www m mmmwmmmmwmmm mwmmmmm? m @www @E .mwmmh Mmmm www .mmmmm um m mmmam umpnwm mum e m awmmn1nn mm m ,m www? mmmmmmmmmmmwmmm mmwmmmmmmdmm w muy@ mmmmmmmm mmmmmmmmmmmmr c m .u u.. ...m m .fm nu 1 med MmmmWmmmmmmmmmmmmmmmmrwmw mmmmmmmmmmmmm m wm www .uw mm .mmm i@ mm? mhmmmmmu ,vwmw mm.mm m :www awww@ mmm L m, hummmMmmmmmmmmmmmmmmmmmmmm,um m mmwmmmmmwwmwwwmmmwmxwdmm U M www m MWWM,... m W. m, mmwmvmmmmwmm mmmmm mmmmmwmmmmmmw @M mmmmwmmmmmmmMmmm .www mmwm mmmmtmmmm .mmmmwmpmmmmmm mmmmmm mmm mm mmwmmdmwmmmm mmm mm..,mm n .mam wb um m .mmm m m mm rw m m n w www mm mmmmmwmwmwww@mwmmmmmmmm M n..." f d m m .m om mm m mm mmmmmmmmmmmmmmmmmmmn ...mim mwmwmu un m@ p mm n o d .5 M ma m mmmmm m mmm r mmmmnmwmwwm mn mw m mmf, mm m mmm u m p me m m www M 2 mmmmm Mmmmmmmmm,mmmmmmmmmmmm
